Endnote 7 CWYW gone

Within the last couple days CWYW disappeared from Word 2003. Endnote 7 works fine and the library is intact but no link to Word. Ive tried the following to fix the problem:

Windows system restore to a date previous to the malfunction,

Reinstalling Endnote, and

Moving the CWYW files around according to the FAQ suggestions at http://www.endnote.com/support/faqs/CWYW/faq1.asp

Interistingly the files were not in the endnote folder where they should have been so I had to download them. But when put in the proper folder still no CWYW.

Thanks for your help.
